BACKGROUND Field of Invention and Prior Art A. Introduction of the Problems Addressed

The growing popularity of the sports, tailgating events and other social and family-type gatherings or outings continues. Along the way, foods have become more in need of temperature control and retention to keep the hot dishes hot and the cold dishes cold. This need has spurred considerable interest in having a better transportable container that can keep foods at the desired temperature level. Since many of the locations where the device is needed lacks easy access to utilities (electricity etc.) there is a problem and need to maintain temperatures without ready access to the electricity. Other problems and needs to address are a properly sized carrier for the food, the storage of thermally controlled devices when not in use, and the ease of use when the user is at the event or gathering.

The availability of a portable, temperature retaining food container with improvements that address these problems described herein is not known in the prior art. More specifically, a portable, temperature retaining food container with good temperature retention—hot or cold—and without electricity; easy portability and easy storage features are heretofore not known to exist.

B. Prior Art

In prior art, disclosures have been made in the field of food temperature control and transporting of containers, but they did not show or anticipate the Charlebois device. For example, a U.S. Design Pat. No. DES 287,921 issued in 1987 to Skamser showed a device that was a sleeve to thermally insulate food. There is no functionality explained, but it appears that it has a flap that closes around the food. No mention of hot or cold elements, straps for carrying or portability are evident so it does not anticipate the Charlebois device. Another device is shown in a U.S. Pat. No. 5,052,369 issued in 1991 to Johnson which demonstrated a heat retaining food container. It is an improved heat retaining foodservice system including a heat retaining food cover, food container and under base, each including a heat storage system comprised of a sealed chamber there within. It shows that the configuration is built-in as a container and not a carrier that may be used with other containers. It does not address cold retention (heat repulsion). It shows no carrying straps or stack ability for storage. Therefore, it does not anticipate or make the Charlebois device obvious to those persons who are skilled in the art.

Turning to other devices, a U.S. Pat. No. 5,892,202 was issued in 1999 to Baldwin et al. The thermal storage and transport device or carrying case for storing and transporting heated articles includes a thermal storage assembly having a heat retention member for absorbing and retaining sensible heat and for releasing the sensible heat of an extended period of time. The thermal storage assembly includes a heating coil assembly secured to a surface of the heat retention member. The heating coil assembly includes a resistive heating coil disposed adjacent to the heat retention member. The heating coil has a power cord connected to the coil with the coil being retained within a sealed thermally conductive pouch. The unit needs to be plugged into electricity to recharge the heat coils, the unit lacks cooling capacity, and it appears as a food vendor's device. Therefore, it does not anticipate or make the Charlebois device obvious to those skilled in the art. Another U.S. Pat. No. 7,491,912 issued in 2009 to Check is a portable container with a temperature control chamber. Check taught a portable food delivery container that includes a food storage compartment, a control compartment, and a temperature control source. A control compartment lies adjacent to and in thermal conductivity with the food storage compartment. A modular removable temperature control source is disposed within the control compartment, where the temperature control source affects transfer of thermal energy between the food storage compartment and the control compartment to maintain the food storage compartment at a temperature other than the ambient temperature. It lacks handles, stack ability, and flexibility to be used with various sized and designed containers owned by the user. Therefore, it does not anticipate or make the Charlebois device obvious to those skilled in the art.

U.S. Pat. No. 6,705,108 issued in 2004 to DeFelice, et al shows a nested cooler system for temporary storage of perishable food stuffs and more particularly to articles for convenient, temporary storage of human breast milk and infant formulas. The inner and outer coolers jointly or independently receive the perishable foodstuffs and freezable gel packs for cooling the perishable foodstuffs. The gel packs can be frozen and thawed several times and temporarily keep containers of milk within an acceptable temperature range to prevent spoilage. The gel packs fit within pockets in the coolers to maintain proper positioning of the gel packs relative to the bottles. It is unlike the Charlebois system that shows a vacuum sealed, insulated liner for the hot and cold retention for the bowls of food. Defelice shows a different manner of only the poly urethane foam and claims only for cold foods—especially infant formula and breast milk. Defelice does not suggest or teach any hot retention. Next Eisenberg et al (US 2009/0232420—now a US Patent 7,992) shows a compartmentalized grocery bag. It fails to suggest or teach any hot retention nor cold packs like Charlebois, nor a zipper, no the nesting features. Finally, patent application US 2003/0178429 submitted by Williams, et al shows a composite container is provided for vacuum packaging of products. It discloses a generally tubular body portion having opposite ends and an inner surface. The liner is not vacuum sealed.

As far as is known, there is no other portable, temperature controlling food container to fully accomplish the objectives and goals of this present device. It is believed that this device is made with fewer parts and with improved configurations and physical features to provide more functionality, when compared to other currently utilized devices or methods for carrying and maintaining temperatures of food. The particular combinations of materials and features are unique and novel. One may conclude that these combinations in Charlebois are not anticipated by prior art.

The preferred embodiment of the Insulated Food Carrying System of Nesting Devices called The Bowl Buddy 31 may be made in various ways and still be within the spirit and scope of the invention. One may see that the prototype may be stamped/cut from structural pieces or from a formable material, then formed and configured to the desired shape. One skilled in manufacturing devices and products similar to the device 31 has a full appreciation of the plethora of processes and materials that may be used to manufacture the nestable, portable, and temperature retaining food container device 31. The sidewall panel 34 and bottom 32 may be contiguous in sheet form or have a joining or means to secure 33 which may require a heat and/or friction welding (plastic), adhesive (plastic, fabric, composites), or a special securing means such as sewing or other fastening means. As a further example and not as a limitation the liner 43 and pockets 40 of the device 31 may be made from a plastic or composite plastic of various types. One suggested material for the liner 43 is presently the preferred material PE/EVA [polyethylene/ethylene vinyl acetate copolymer]. The fabric for the exterior surfaces may be of fabric, canvas, treated cotton, composite materials (nylon, rayon, a polyester, co-polyesters and the like and may be suitable for the panel 32, bottom 33, lid 36 and some variations for the liner 43 and/or handle/strap 35. These are offered for example and not as a limitation. Anticipated in the scope is the air gap or insulative material 44 juxtaposed between the exterior surfaces and the liner 43 of the aforementioned components 32, 34, and 36. Each bowl buddy 31 is specially designed with the unique material. Another specific but not limiting watertight fabric was specified on the initial prototypes as Fabric 600D with Lining: 190T (waterproof) or equal. This design has the closed cooling and heating compartments/pockets 40 also made from watertight materials to provide the most optimum temperature retention results. The food containers 55 (such as plastic snap-tops through ceramic or glass containers) are user furnished by the user 60 and may be placed in one of the three (3) included and nested sizes that matches the size of the device 31 to the size of the food container 55.

All of the details mentioned here are exemplary and not limiting. Other components specific to describing the nestable, portable and temperature retention food container device may be added, as a person having ordinary skill in the field of portable, temperature retaining containers well appreciates. It will be apparent to those skilled in the art that various modifications and variations can be made in the configuration and materials of the present invention without departing from the scope or spirit of the invention. As an example, various materials of construction may be used for present invention, as long as the materials are lightweight. As another example, various dimensions may be employed for the device and its components. Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the claims which follow.

OPERATION OF THE PREFERRED EMBODIMENT

The preferred embodiment of the Insulated Food Carrying System of Nesting Devices called The Bowl Buddy has been described in detail above. The manner of how the device operates is described below. A person having ordinary skill in the field of portable, temperature retaining containers and related devices in the food preparation and care industry, will note that the description above and the operation described here must be taken together to fully illustrate the concept of the special device 31.

FIGS. 1 D and 1 E, 3 B, and 4 A through 4 C show the Bowl Buddy device in operation and use. These are shown and explained here.

FIGS. 1 D and 1 E general operation sketches of the Insulated Food Carrying System of Nesting Devices 31 called The Bowl Buddy. FIG. 1 D shows the device 31 with the food unit 55 placed inside the liner 43 with the lid 36 removed. FIG. 1 E shows the small device 31A being placed into the medium device 31B by the user 60. The relative larger device 31C is placed nearby. The action by the user 60 demonstrates the stack ability of the units for storing, moving or for packaging at the initial sale. Note the relativity of small, medium and large is in comparison to each other and to the food containers 55. One notes the cylindrical shape is a tighter fit to the round bowls and containers. This permits the individual devices to “hug” or tightly control the round bowls which reduces movement of the bowl and its contents. This helps prevent spillage and content shifting. When contents are allowed to “shift” the movement can cause droppage or spills.

FIG. 3 B shows a sketch of a person 60 using the device 31. Here the person 60 is placing a hot/cold element pack 39 into the pocket 40 and closing the securing means 41 such as a flap with Velcro™ hook and loop mechanism.

FIGS. 4 A through 4 C are sketches of the nestable and insulated food carrying device in use. FIG. 4 A shows the device 31 with the food unit 55 placed inside the liner 43 with the lid 36 removed. Also one may note the means 37 (such means 37 being a zipper [two-way], Velcro™ hook and loop mechanism, a series of snaps or equal). to secure the lid 36 to the side panel 34. In FIG. 4 B, a person/user 60 is shown with the device 31 being carried on the shoulder of the user by the handle 35 or strap. FIG. 4 C demonstrates the small device 31A being placed into the medium device 31B by the user 60. The larger device 31C is placed nearby.

Very simply stated, the device 31 is used by a person 60 as follows:

-   -   1. The device 31 is removed from storage;     -   2. The means 37 to removably attach the lid 36 to the sidewall         panel 34 is opened or disengaged;     -   3. One or more of the devices 31A, 31B, and/or 31C is chosen for         use with a food unit container 55;     -   4. A set of pre-conditioned hot/cold elements 39 are placed into         the pockets 40 and the means 41 to secure the elements 39 inside         the pocket 40 is closed;     -   5. The food container 55 with hot/cold food 50 is placed inside         the device 31, the container 55 being contiguous to the liner 43         and pockets 40;     -   6. The lid 36 is placed on top of the panels 34 and the means 37         to secure the lid 36 to the sidewall panel 32 is engaged;     -   7. The straps 35 are grasped by the user 60 for transport to the         place of use;     -   8. And at the place of use, the means 37 is disengaged and the         lid 36 is removed from the sidewall panel 34 for easy access to         the food 50 in the food container 55.     -   9. After use the previous steps are essentially reversed and the         device 31 is re-nested and returned to storage.

The Insulated Food Carrying System of Nesting Devices device may be used in many ways with different foods. For example and not as a limitation uses are anticipated as with:

Item Use 1 Great for salads 2 Cakes 3 Veggie trays 4 Fruit bowl 5 Pasta 6 Wings 7 Dips/soup 8 Soups 9 Lunches

The terms recited in the claims should be given their ordinary and customary meaning as determined by reference to relevant entries (e.g., definition of “plane” as a carpenter's tool would not be relevant to the use of the term “plane” when used to refer to an airplane, etc.) in dictionaries (e.g., widely used general reference dictionaries and/or relevant technical dictionaries), commonly understood meanings by those in the art, etc., with the understanding that the broadest meaning imparted by any one or combination of these sources should be given to the claim terms (e.g., two or more relevant dictionary entries should be combined to provide the broadest meaning of the combination of entries, etc.) subject only to the following exceptions: (a) if a term is used herein in a manner more expansive than its ordinary and customary meaning, the term should be given its ordinary and customary meaning plus the additional expansive meaning, or (b) if a term has been explicitly defined to have a different meaning by reciting the term followed by the phrase “as used herein shall mean” or similar language (e.g., “herein this term means,” “as defined herein,” “for the purposes of this disclosure [the term] shall mean,” etc.). References to specific examples, use of “i.e.,” use of the word “invention,” etc., are not meant to invoke exception (b) or otherwise restrict the scope of the recited claim terms. Other than situations where exception (b) applies, nothing contained herein should be considered a disclaimer or disavowal of claim scope. Accordingly, the subject matter recited in the claims is not coextensive with and should not be interpreted to be coextensive with any particular embodiment, feature, or combination of features shown herein. This is true even if only a single embodiment of the particular feature or combination of features is illustrated and described herein. Thus, the appended claims should be read to be given their broadest interpretation in view of the prior art and the ordinary meaning of the claim terms.

Unless otherwise indicated, all numbers or expressions, such as those expressing dimensions, physical characteristics, etc. used in the specification (other than the claims) are understood as modified in all instances by the term “approximately.” At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the claims, each numerical parameter recited in the specification or claims which is modified by the term “approximately” should at least be construed in light of the number of recited significant digits and by applying ordinary rounding techniques.
